Examples of GinjectorBindings

com.google.gwt.inject.rebind.GinjectorBindings
Stores information that describes the bindings present in a given injector, and the relationship to the other injectors in the hierarchy. This class is used in two stages:
- During bindings processing {@link BindingsProcessor} thisgathers up explicit bindings and unresolved dependencies. After all bindings have been gathered from the modules, {@link #resolveBindings} is called inthe last stage of processing and it is finalized. After that point, no new unresolved bindings should be added.
- At this point, it is ready to be used by {@link GinjectorOutputter} forgenerating the Ginjector implementation. In this stage several additional methods are available for getting information about the code that has been generated to represent this ginjector.
Each {@link GinjectorBindings} can have a parent ginjector, and any number ofchild ginjectors.
